JOSEPH BEN. FAULKNER, OF CAB'TERSVLLE, GEORGIA.

GASOLENE-TANK INDICATOR.

Specification of Letters Patent. Pgitlld litl. 22, 19:21.

Application led November 21, 1919. Serial No. 339,554.. Y

To all whom it may concern.'

Be 1t known that I, JOSEPH BENJAMIN 'FAULK'NEma citizen of the United States,

'Y residing at Cartersville, in the county of Bart-ow, State of Georgia, have invented certain newl and useful improvements in Grasolene-Tank Indicators, of which the following is a description, reference being had to theaccompanying drawings, forming a part hereof.

' My invention relates to float indicators for indicating at a distance the height of .Y liquidin a tank and relates particularly to VVdevices of this character for indicating on the dash or instrument board of an automobile the amount of gasolene in the gaso- `Vith the above explained objects in view my invention consists in the construction and combination of elements hereinafter described and claimed.

VIn the drawings Figure 1 is view in elevation of the indicating device of my invention with the front or cover glass and dial yremoved to show theoperating parts.

Fig. 2 is a side view partly in section of the'indicator controlling means located at the gasolene tank.

Fig. 3 is a vertical sectional view on line Y 3-3 of Fig. 2.

Fig. 4 is a vertical sectional view on line 4*-4 of Fig. 2, and

Fig. 5 is a front elevation of the indicating device as it appears on the dash or indicating board. Y

In the 'drawings 1 Vindicates a float carried by an arm 2 pivoted at 3 to a post 4 adapted to extend downward into the gasolene or other tank from a box 5. Vithin the box 5 is arranged a shaft 6 carrying a gear 7 which meshes with a gear 8 on which is secured a radialarm 9 the outer end of which v is connected by4 a link .10 with the arm-2 which carries the iioat 1. The shaft 6 ex- 1 tends through the side of box 5 and. within aV pipe 11, to asecond box 12. Within this vsecond box 12 is arranged a short tube 13 of insulating material having on its interior a series of contact blocks 14, 15, 16, and 17 here shown as four in number though a greater or smaller number may be used. A contact brush 18 carried by the shaft 6 is adapted to make contact with any of the contact blocks according to .the position to which the shaft 6 is rotated as hereinafter described. From each of the contact blocks 14, 15, 16, and 17 a wire leads to the indicator these wires being marked respectively 20, 21, 22, and 23. A pipe 24 preferably extends from the box 12 to the indicator to protect the wires from injury. A wire 19 leads to the shaft 6 from any convenient source of electric current.

rlChe indicator casing 25 preferably of the form shown in Figs. 1 and 5 is adapted to be carried on the instrument board. This yindicator casing has within it a suitably marked dial and preferably has a glass front. Pivoted within it is an indicator needle 26 suitably balanced and having at its lower end an armature 27. In the lower half of the indicator casing is arranged a series of electromagnets 30, 31, 32, and 33 corresponding in numberwith the contact blocks above described one end of the winding of each electromagnet being connected by a wire with a contact block, 30 being connected by wire 2O with contact block 14, 31 being connected by wire 21 with contact block 15. 32 by wire 22 with contact block 16, and 33 by wire 23 with contact block 17. The other ends of the windings of these electromagnets are all connected to one terminal of a push button switch 34 and the other terminal is connected by wire 35 to the source of current to which wire 19 is connected.

`The height of the liquid in the gasolene tank determines the position of the float 1,

the iioat gradually dropping as the gasolene ing, the circuit, however not being complete so long as the switch 34 remains open. On pressing the button to. close this switch the circuit is completed from the source of current through Wire 19, sliai't 6, brush 1S, one of the Contact blocks, i'cs Wire and the Winding' of an eiectroinanet, tliuS energizing that electromagnet and causing it to attract the armature 2T and swing; the needle 26 to' a position corresponding to the position of the ioat thus showing lionY Inucli gasolene there is in the tank.

While die inven'ion has been above described as particularly adapted and inended for use y'ith a gasolene tank on an automobile it is not intended to limit it to such use as it is adapted for nee in indicating the amount of liquid in any bank or Vessel and may be used with Water tanks or any other tanks, lie indicator being` located at any desired distance from the tank.

aving thus described my invention what claim is;

)i ioat actnaed circuit closer comprising a gear. a radial arm carried by the gear, a lever inlcrinned aitone end and provided with a ioat at its rec end, a link Qivotally fonnected ai; one end to the radial arm and at the other end to Jdie lever between its ends, a Shaft in circuit Wili a source of current provided with a gear in rneeli wih the first mentioned gear, a brush carried by the shaft, and a series of contacts in the pai'b of morenient oli' lie brneli.

In tesiviinony wheres-' allix my signaiiire liis 21st day of November, 1919.
